High levels of species richness in mountains are associated with their hypothetical roles as cradles and/or museums of diversity, but the generality of these roles remains unknown. To fill this gap, we tested these two hypotheses at a global scale and assessed the direct and indirect effects of abiotic regional features on the variation of montane amphibian richness world‐wide.

进化时间，物种形成速率和局部非生物条件对两栖类山地生物多样性的起源和维持的影响

山区丰富的物种丰富度与其作为摇篮和/或多样性博物馆的假想角色有关，但这些角色的普遍性仍然未知。为了填补这一空白，我们在全球范围内测试了这两个假设，并评估了非生物区域特征对全球山地两栖动物丰富度变化的直接和间接影响。
